A shooting at a Detroit recreation center has left one person dead and a mother and son charged with murder.

Wayne County Prosecutor Kym Worthy announced charges against 35-year-old Terranisha Davis and her 15-year-old son, Tremaine. The Detroit Free Press reports the teen will be tried as an adult. Both face life in prison.

The Detroit News reports that the younger Davis got into an argument with someone outside the Considine Recreation Center on Oct. 8. Mother Davis unlocked the hood of her car so that her son could retrieve a revolver hidden inside.

The younger Davis shot 19-year-old Demitry Jackson in the head. Police originally thought Jackson was arguing with Davis, but it turns out he was an innocent bystander.

The woman and her son drove away from the scene, but were arrested a short time later.
